Consuming MCP Servers from .NET: The Client Side
Most MCP writing is about building servers. The harder engineering is on the client — you are handing a model a tool list you did not write, from a process you did not start, and it can change under you at runtime.
Human-in-the-Loop Approvals in Microsoft Agent Framework
An agent that can issue refunds needs a stop button. Agent Framework has two mechanisms for this — tool approval and workflow request ports — and picking the wrong one leaves you holding state you cannot survive a restart with.
CodeAct in the Microsoft Agent Framework: What .NET Developers Need to Know
CodeAct collapses the tool-calling loop into one generated program and reports large latency and token savings — but it is Python-only today. What it is, why it works, and what a .NET team can use right now.
Migrating from Semantic Kernel to the Microsoft Agent Framework: A C# Walkthrough
A line-by-line C# migration from Semantic Kernel agents to the Microsoft Agent Framework — namespaces, agent creation, threads, tools, invocation, options and DI, with before/after code for each.
The A2A (Agent2Agent) Protocol for .NET Developers
What the A2A (Agent2Agent) protocol is, how it differs from MCP, and how .NET developers build A2A agents in C# with the A2A SDK and Microsoft Agent Framework.
The Agent Harness in Microsoft Agent Framework (.NET Guide)
The Agent Harness in Microsoft Agent Framework gives .NET agents sandboxed shell execution, file access, and human-in-the-loop approvals. How to wire it up.
Agent Skills for .NET: A Practical Guide
Agent Skills for .NET is now stable in the Microsoft Agent Framework. Learn how to package, distribute, and govern agent skills in C#, with working code.
Hosted Agents in Foundry Agent Service: A .NET Developer's Guide
Hosted agents in Foundry Agent Service are GA: per-session sandboxes, scale-to-zero, and a simple path to deploy Microsoft Agent Framework agents from .NET.

Build 2026 for .NET agent developers: Agent Harness, Hosted Agents, Agent Skills, CodeAct, and Foundry IQ memory — what shipped, why it matters, what to do.
Build Your First Tool-Using AI Agent in C#
A step-by-step tutorial: build an AI agent in C# with the Microsoft Agent Framework that calls your own tools, remembers the conversation, and chains multiple tool calls.
Multi-Agent Orchestration in .NET: Graph Workflows Explained
Coordinating multiple AI agents by prompt alone is fragile. Here is how the Microsoft Agent Framework's graph-based workflows make multi-agent systems in .NET explicit, testable, and observable.
Semantic Kernel vs the Microsoft Agent Framework: Which Should You Use in 2026?
Semantic Kernel or the Microsoft Agent Framework? Since the 1.0 GA merge, the answer changed. A clear breakdown of what to use for new projects and how to migrate existing ones.
The Microsoft Agent Framework for .NET: A Developer's Guide
Microsoft Agent Framework 1.0 unifies Semantic Kernel and AutoGen into one .NET SDK for building AI agents. Here is what it is, why it exists, and how to build your first agent in C#.
Model Context Protocol for .NET Developers: Giving Your Agent Real Tools
A practical guide to Model Context Protocol (MCP) for .NET developers: connect a Microsoft Agent Framework agent to an MCP server and expose your own agent as one.
